Just this morning as I was mowing my 2000 Great Dane Scamper suddenly stopped driving. I tried setting the throttle in different positions, and other things, but nothing worked to get it moving again. I thought it had to be a broken engine-to-hydro belt (I had this same problem before on my previous Great Dane, and a new belt fixed it). I shut the mower down, then restarted it. I noticed that the hyrdos sounded like they were pumping as normal. I could distincly hear them like I always have. I have not looked under yet to confirm that the belt is still intact. The hydros are the "integrated hydro" style, which means the wheel motor and hydro are in one unit. What do you think is the problem? I thought I had heard somewhere about these hydros being problematic. I will need help as to what this problem is immediately, or else I'm going to have to mow my 2-acre yard with a push mower out in 90 degrees. Thanks alot for your help.
